Sub-kpc scale gas density histograms of the nearby barred spiral galaxy M83: Multi-component molecular gas structure reflecting the galactic environment
Ren Matsusaka, Toshihiro Handa, Fumi Egusa +8
We investigate the sub-kiloparsec (sub-kpc) molecular ISM structure and its relation to the galactic environment and star formation in the barred spiral galaxy M83 (NGC 5236). We e…
Axisymmetric Jeans modelling systematically overestimates the circular speed in the inner Milky Way
Tomoki Yamaguchi, Junichi Baba
We quantify systematic biases in rotation curves inferred from steady, axisymmetric Jeans modelling when the underlying stellar velocity field is non-axisymmetric. Using a high-res…
Anomalous fractional quantization in the kagomelike Heisenberg ladder: Emergence of the effective spin-1 chain
Tomoki Yamaguchi, Yukinori Ohta, Satoshi Nishimoto
We study a Kagome-like spin- Heisenberg ladder with competing ferromagnetic (FM) and antiferromagnetic (AFM) exchange interactions. Using the density-matrix renormalization gr…
Slow dynamics of disordered zigzag chain molecules in layered LiVS2 under electron irradiation
Naoyuki Katayama, Keita Kojima, Tomoki Yamaguchi +8
Electronic instabilities in transition metal compounds often spontaneously form orbital molecules, which consist of orbital-coupled metal ions at low temperature. Recent local stru…
Pressure-Induced Restoration of the Reversed Crystal-Field Splitting in -SrCrO
Ryo Takahashi, Tomoki Yamaguchi, Koudai Sugimoto +3
Motivated by an experimental finding that the successive phase transitions in -SrCrO observed at ambient pressure ceases to exist under high pressures, we carry out the…
Variety of order-by-disorder phases in the asymmetric zigzag ladder: From the delta chain to the chain
Tomoki Yamaguchi, Stefan-Ludwig Drechsler, Yukinori Ohta +1
We study an asymmetric - zigzag ladder consisting of two different spin- antiferromagnetic (AFM; , ) Heisenberg legs coupled by zigzag-shaped fe…
